Title: Improvements in or relating to winches for use with dye cisterns and like vessels
IPC: D06B3/26
Filed: 1933-11-24
Abstract: <PICT:0422082/IV/1> A winch for dye cisterns and the like has a barrel provided with narrow longitudinal ridges between which are wide shallow cavities.  The material in passing over the barrel partially sags into the cavities causing a momentary lessening of air pressure on the underside of the material.  Transverse ridges may also be provided.  As shown, a winch 1, either hollow and of stainless steel, or solid and of wood, is provided with ridges 2 which form recesses 3.  Where the winch is hollow, the sheet metal, jointed at 7, is disposed on bars 6.  The cavities may be further divided by ribs transverse to the ridges 2.  The fabric may be guided to prevent lateral movement between clips on rods 10 disposed in the cavities 3.  In operation, a partial vacuum is created in the cavities which further aids the grip on the material.  The cavities also form temporary reservoirs for moisture from the material.  The cistern 22 comprises a wooden frame with a stainless steel lining 24 and a perforated screen 25 through which the dye circulates under the influence of a heating element in chamber 27.

Title: Improvements relating to internal combustion engines
IPC: F01L1/28
Filed: 1934-11-19
Abstract: 446,692. Valves; pumps. CROSSLEYPREMIER ENGINES, Ltd., and YEATES, A. C., Sandiacre, near Nottingham. Nov. 19, 1934, No. 33299. [Classes 7 (ii) and 7 (vi)] In a gas engine, a main inlet valve a carries on its stem a gas-inlet valve d connected to a slide valve b controlling inlet of compressed air through ports c, the arrangement being such that, when the valve a commences to open on the inlet stroke, compressed air is first admitted through the ports c to scavenge out the exhaust gases, after which the valve d is opened to admit gas from the passage e, while just before the valve a closes again, compressed air is again admitted through the ports c. The gas valve d is loose on the stem of the valve a, being pressed to its seat by a spring f inside the valve, and has a piston-like extension on its head which obstructs the inlet of gas until the valve a has opened a certain amount. By removing the valves band d, and cutting off the gas supply, the engine may be converted into an oil engine, the valve a serving to admit air under pressure only. Where air is supplied to a multicylinder engine by a rotary blower, a byepass valve between the suction and delivery sides of the blower may be actuated so as to open when all the poppet valves or the slide valves are closed, thus allowing delivery of air by the blower only when the valves for admitting the same are open.

Title: Improvements in or relating to electrical systems for determining the direction of sound sources
IPC: G01S1/72
Filed: 1938-11-18
Abstract: 579,360. Directional reception of wave energy. CLARK, H. A. M. Nov. 18, 1938, No. 33504. [Class 118 (ii)] [Also in Groups XXXV and XL] The invention relates to'the method described in Specification 578,729 of conveying directional intelligence by means of a cathode ray tube to the deflector plates &c. of which are applied "sum" and "difference" outputs obtained by the interaction of the outputs of a pair of vibratory or radiant energy detectors, and consists in the provision of electrical circuits whereby the electron beam of a single cathode ray tube is caused to trace two lines independently controlled by separate outputs relating respectively to azimuth and zenith angles. As shown, the outputs of zenith microphones 1, 2 and azimuth microphones 3, 4, after conversion into sum and difference outputs, amplification and phase modification in the channels ZC and AC (all as described in the above-mentioned specification) are fed alternately to the oscilloscope via a switching device comprising four valves V2, V4 and V1, V3, each pair of which is made operative in turn by the application to their inner grids G1-G4 of varying potentials derived from a push-pull oscillator SC. The output circuits ZS, ZD and AS, AD are connected to the outer grids OG1-OG4, the anodes and cathodes of valves V1 and V2 being connected in parallel across the vertical deflector plates D1, D2, while those of valves V3 and V4 are connected across the horizontal plates D3, D4. The electron beam may be "blacked-out" during the actual switching by applying, to a control grid CG in the oscilloscope, a negative potential derived from an inductance L2 coupled to the cathode circuit of the valves of the push-pull oscillator SC. A diode V7 is interposed to prevent the grid CG becoming positive. To avoid duplication of the amplifying and phase modifying means in each of the channels ZC, AC, such means may be interposed between the valves Vl-V4 and the oscilloscope (Fig. 2, not shown). Means are also described whereby a common reflector in which the four microphones are mounted is rotated about vertical and horizontal axes by two series-wound electro-motors, the direction and strength of the armature current of which is varied by potentiometers controlled by the operation of two pointers pivoted over the centre of the oscilloscope screen and movable manually to coincide with the direction of the two traces (Fig. 3, not shown). Alternatively, the reflector or reflectors may be caused to follow the sound source by motors controlled by thermionic or gas discharge valve relays responsive to the input to the oscilloscope deflector plates.
